Mg–air oxygen shuttle batteries using a ZrO2-based oxide ion-conducting electrolyte

Abstract

A new concept of an "oxygen shuttle" type battery for Mg-air solid oxide batteries using a Ca-stabilized ZrO2 electrolyte was proposed and studied. The observed open circuit potential and discharge capacity were 1.81 V and 1154 mA h gMg(-1) (52% of the theoretical capacity), respectively.

A Multi-Physics Model for Solid Oxide Iron-Air Redox Flow Battery: Simulation of Discharge Behavior at High Current Density

“…[5][6][7][8][9][10][11][12][13][14][15][16][17][18] Although the operating temperature, geometries and configurations for the flow battery systems reported in the literature vary to some degree, our multi-physics model presented here is developed for a close-loop tubular battery reactor working at 800…”

“…[1][2][3][4] Recently, a distinct group of solid oxide redox flow batteries targeted at stationary energy storage was developed based on the technologies of reversible solid oxide fuel cell (RSOFC) and H 2 chemical looping. [5][6][7][8][9][10][11][12][13][14][15][16][17] The nature of this type of metal-air battery is the use of solid O 2− conducting electrolyte. The uniqueness of this new battery is manifested by the fact that the electrical energy conveyed by RSOFC can be reversibly converted into chemical energy by a physically separated metal-metal oxide (Me-MeO x ) redox couple.…”

Heat Balance in a Planar Solid Oxide Iron-Air Redox Battery: A Computational Analysis

“…The advantages of SOMARB include double electron transfer (O 2− ), energy storage in a chemical bed separated from the electrode, fast charging and discharging rate, use of earth-abundant element such as iron for energy storage, scalability and operational safety. Since its debut in 2011, 1 significant progress has been made in the areas of electrochemical performance optimization, [2][3][4][5][6][7][8][9][10][11][12] new metal-air chemistries [13][14][15][16][17][18][19][20] and multiphysics modeling of electrochemistry, mass transport and chemical redox kinetics that govern the electrical behaviors of the battery.
